I am relatively new to the mirage drive. The stablizing bar(?) that runs down one of turbo fins has become exposed...about an inch. the other side seems to be attempting to push through. I might have damaged then in a couple of different circumstances but don't remember anything drastic.

Have any of you experienced this?Should I expect the tear to get worse with use?It appears the fins can be replaced?

After you fix or replace the damaged fins, you might want to cover the area with some tape. It will help prevent damage in the future when hitting rocks, sand bars, etc. I use 3M clear duct tape and it's been on for almost a year.
